My invention relates to landmarkers and its primary object is theprovision of landmar or structure which will be automatically missed andlowered. whenever the plows are raised and lowered.

Another of my objects is the provision of adjustable features wherebythe marker arm may be adjustably supported in accordance with the depthof plowing.

Another of my objects is to provide a markor structure which is adaptedfor use on listers so as to mark the new row parallel to a previousfurrow.

Still another of my objects is the provision of a marker structure ofextreme simplicity and which is operable without requiring any attentionother than the original adjustment;

Having in view these objects and others which will be pointed out in thefollowing description, T will now refer to the drawings, in which Figure1 is a view in rear elevation of the marker arms, the markers, the supports and including also a sectional View of the lister plow beams andseat beam showing 25 the relation of the marker arms to the implementframe.

Figure 2 is a view in side elevation of a lister with the markerattached thereto, only such parts of the lister being shown as are sonecessary to disclose the relation of the markor to the lister.

Figure 3 is a plan view of the lister and marker shown in Figure 2.

The lister here shown consists of a front frame and a rear frame whichare pivotally connected together, the front frame carrying the listerplows. J-ls shown, the plow beams are parallel and they have securedthereto and between them a more or less U- haped frame 11. To thetransverse portion of the frame member 11 is pivotally secured a bailaxle 12 having rear supporting wheels 13. The forward ends of the plowbeams 10 are supported on caster wheels it as best shown in Figure 2.Extending rearwardly from the forward part of the implement frame is aseat supporting beam 15 which is supported in its rear portion on therear wheel support by means of one or more supports 16. F rward of theseat 17 is a lever 18 with appropriate latching mechanism for elevatingand lowering the pivotal point of the members 11 and 12. It obvious thatwhen this pivot is raised the plow bodies are raised and that the plowbodies may be lowered by manipulating the lever 18 so as to lower thepivot. The seat beam 15 remains substantially stationary throughoutthese movements because both. its front and rear ends are at fixedheights above the surface of the soil. The wheels 13 and 1%, however,approach each other when the plows are raised. The lister abovedescribed carries two plow bodies 19. in carrying out-the invention abracket 20 is secured by means of-bolts or the like to the seat beam 15.The two arms .21 are each hinged to the bracket 20 by means oflongitudinally positioned pins. Each arm carries a marker member 22 ofany desired design at its outer extremity. The marker arms 21 are bracedby means of forwardly and inwardly extending braces 23 terminating atthe forward ends of the plow beams 10.

Since the seat beam 15 is in a more or less fixed position above thesurface of the soil, the pivots and therefore the inner ends of themarker arms 21 will be at a constant level above the surface of thesoil. The marker arms, however, rest on the plow beams 10 so that everychange in the elevation of the plow beams 10 is communicated to theouter ends of the marker arms 21 and therefore to the marker members Themovement will, of course, be considerable because of the leverageexerted on the arms 21. It will be obvious from the foregoingdescription that whenever the plows are raised out of the ground themarker arms will be moved on their pivots until the marker members ofthe upper ends of the arms will be high enough to clear allobstructions.

Furrows out at various depths and provision has been made forappropriate adjustment to take care of those varying depths. Forthispurpose there is employ d a wedge block 24L on each arm 21. The we eblock tapers throughout a portion of its lei 'h and it is provided witha plurality of apertures through which bolts may be passed and throughthe arms 21. These bloclrs may be ice I moved inwardly to elevate theouter extremities of the arms 21 or outwardly to lower them. Theyprovide a considerable range of adjustment but when this is found to beinsuflicient, the blocks 24 may be reversed in end to end relation tostill further increase the range of adjustment. The device is, however,provided with other adjusting features which materially increase therange'of adj us tment of the marker arms. :In the :pivotal connectionsbetween the marker arms 21 and the bracket 20 it will be noticed thathinge straps are secured to the marker arms on their lower surfaces "sothat "the hinge pins are in alignment with the lower surfaces of thearms. Thehinges are provided with removable pins so that when it isdesired to swing the markermem'bers 22 through an are at a higher level,it isonly'necessary to turn the markerarmsbotto mside up'and'to insertthe pivot pins,:after which'the marker mem- 'bers"22must"also bereversed. Should still further adjustment be needed the wedgeb'locks'maynlso be employed.

When used with a t-wo row lister such as that shOwnFi'nthedrawings, oneofthe marker members 22 isallowed to ride'in the previous fu'rrow'sothatt'he'other marker mem- 'ber'2 2'will mark the lineof the new furrow.At 'the end of the furrow t'he plows and the marker'members 22 "areraised simultaneous- 'ly and the implement is turned around to "travelin the opposite direction.

course, reverses the positions of the two marker members so that themember 22 which formerly served as a guiding member now serves asa'marker member.

2. In combination, a tillage implement including an implement frame, abeam pivotally connected thereto, a tillage tool secured tosaid beam atthe free extremity thereof, means for moving said beam on its pivot toraiseor lowersaid tool, and a marker arm pivotallyconnected at one ofits extremities to said "implement frame to overlie and to rest on saidbeam whereby the raising and lowering of said tillage tool causes theraising and lowering of the free extremity of said marker arm.

4. A landmarker adapted for attachment to a soil tillage implementhaving a beam supported tillage tool,-the beam being pivotally securedto the implement frame and being movable on its pivotal connection toraise and lower the tillage tool, said landmarker including an armadapted to be pivotally secured to a fixed portion of the implementframe in a manner so as to overlie and-to'be supported by the beam ofthe tillage tool whereby the raising or lowering of the tillage toolcauses the raising or lowering of the free extremity of said arm, and awedge block securedto the under side of said arm, said wedge block beingadjustable in the direction of the "length of said arm.
